Recently, a reader left a message, saying "I want to switch to audio and video development, how to do it", just a few days ago I was still on Benhu, and I saw someone asking about audio and video learning materials, and I was still a freshman.
I want to say one thing: really insightful.
In this era, if you want to make money, there is a consensus that you have to choose the right track first . In some industries and fields, the ceiling for a lifetime is nothing more than that. But in some sunrise industries, you can get a lot of opportunities as soon as you enter, that is, "ROI (input-output ratio)
)” is very high. Let’s talk about why you are engaged in audio and video technology, and it will be very profitable in the future. Speaking of audio and video technology, it has ushered in an explosive period in the past two years. First of all, the development of 5G provides hardware conditions, and is also affected by the epidemic. , the online life scene , a large number of online office, online education, online entertainment and other needs, so that hundreds of millions of people poured into various online interactive platforms. For example:
- Short videos of Douyin and Kuaishou require image processing and video encoding
- Technology, how to minimize the size of video files while maintaining high image quality;
- Lianmai live broadcast requires RTC and live broadcast technology, how to ensure ultra-low latency and reduce freeze rate under various network conditions;
- Video conferencing requires technologies such as RTC and transcoding confluence services. How to ensure smoothness, freeze rate, image quality and other indicators for large-scale video conferences with dozens or hundreds of people;
- With the increase of online experience, people's requirements for audio experience in interaction are also increasing. In addition to being able to hear and hear clearly, it must also be pleasant to hear and have a high degree of sound quality reproduction. For example, Facebook changed its name to Meta to enter the metaverse, and TWS headphones support spatial audio rendering and active noise reduction, etc.
It can be said that audio and video technology is like air and water , everywhere, and the future is full of infinite possibilities. Moreover, these real scenes all emphasize real-time interaction , and the delay must be controlled within milliseconds. If there are high delays, freezes, blurred images, and loud noises during this process, can you imagine what kind of experience it will have? Not to mention that Li Jiaqi’s double 11 live broadcast brought in 10 billion goods, and it’s normal to play the King’s Glory with smooth communication
Not necessarily. In fact, as early as the early stage of the epidemic, many SaaS platforms and even large manufacturers had problems with freezing, mainly because they were not fully prepared for the sudden traffic. Now that everyone has seen the online market, there is naturally a demand for audio and video technical talents That's more. So it is no exaggeration to say that audio and video development is a blue ocean with few people and a lot of money .
And in the future, it will be even hotter.
This picture is for reference. But it can also be seen that the overall salary is much better than that of ordinary developers. Not only that, but if you search on the Internet, you can see that a certain Android converts audio and video, which is really delicious, breaks through the employment crisis, and so on.
Nowadays, in addition to big factories, many small companies are also looking for audio and video talents. There may be 3 to 4 companies competing for audio and video talents at the same time. It is because of the low base of practitioners, the lack of high-end talents, and most importantly, the development threshold of audio and video technology, which is not easy to cultivate, and it is also difficult to learn by yourself. But this also means that you have a technical core competitive advantage compared with others, and there is a watershed.
Is there a way to quickly get started with audio and video technology?
It is not easy to learn audio and video technology, and there are too many things to understand: audio and video collection, encoding, transmission, decoding, rendering, etc., and there are few systematic materials on the Internet. But just like the mouse with the left ear said, "Learn from the source of knowledge" . For learners, finding high-quality information sources can make you get twice the result with half the effort, not second-hand processing, and there will be no loss or error of information.
It takes roughly 6 stages to learn and engage in audio and video development, which are
1. Audio and video basics → 2. ffmpeg actual combat → 3. Streaming media client → 4. SRS streaming media server
→5.webRTC in action→6.AndroidNDK
